Open publisher page 20 citations

Abstract

H-NMR spectroscopy. More than 130 compounds were identified. The oils differed in the quantitative composition. The principal components of the oil from twigs with needles were α-pinene (36.3%), limonene (22.7%) and β-phellandrene (12.0%). The needle oil was dominated by α-pinene (48.4%), whereas in the oil from bark and in the oil from twigs without needles there were limonene (36.2% and 33.6%, resp.) and β-phellandrene (18.8% and 17.1%, resp.). The main constituents of the wood oil as well as cone oil were α-pinene (35.2% and 39.0%, resp.) and β-pinene (10.4% and 18.9%, resp.). The wood oil and the cone oil contained large amounts of oxygenated diterpenes in comparison with needle, twig, and bark oils.
